To calculate the volume of the box, you use the formula:

\[ \text{Volume} = \text{Length} \times \text{Width} \times \text{Height} \]

Given:

  • Length = 2 feet
  • Width = \( \frac{1}{4} \) foot
  • Height = \( 1 \frac{1}{5} \) feet

First, convert the height to an improper fraction: \[ 1 \frac{1}{5} = \frac{5}{5} + \frac{1}{5} = \frac{6}{5} \text{ feet} \]

Now, substitute the values into the volume formula: \[ \text{Volume} = 2 \times \frac{1}{4} \times \frac{6}{5} \]

Calculating step by step:

  1. Multiply the length and width: \[ 2 \times \frac{1}{4} = \frac{2}{1} \times \frac{1}{4} = \frac{2 \cdot 1}{1 \cdot 4} = \frac{2}{4} = \frac{1}{2} \] feet²

  2. Now multiply by the height: \[ \frac{1}{2} \times \frac{6}{5} = \frac{1 \cdot 6}{2 \cdot 5} = \frac{6}{10} = \frac{3}{5} \] cubic feet

So, the volume of the box is \( \frac{3}{5} \) cubic feet.

Among the given options, the correct response is:

3 fifths cubic foot.
